A few tips to make this simple salad fantastic – buy baby arugula, it has a milder peppery flavor. Use extra virgin olive oil, and a really good aged balsamic vinegar and most importantly use a premium imported parmesan such as Parmigiano Reggiano for optimum results. If you can’t find it in your area or if it’s out of your budget, Locatelli Pecorino Romano is another great option.
